Kenneth Rosen Edition 6th Exercise 1.3 Example 17 (Page No. 38)
The restriction of a universal quantification is the same as the universal quantification of a conditional statement. For instance, ∀x < 0 (x2 > 0) is another way of expressing ∀x(x < 0 ... whereas existential quantification is same as existential quantification of a conjunction? Please provide proper details. Thank You.
